ton and trise spec of TPS22966

Other Parts Discussed in Thread: TPS22966, TPS22968, TPS22960

Please let me know about TPS22966's t_on and t_rise spec on "VIN=VON=1.8V、VBIAS=3.3V" condition.

Customer request spec is： t_on + t_rise/2 < 1ms

I imaged by nealy spec on datasheet, but it was very subtle line of OK/NG. 

I want concrete spec.

 

Best regards,

Satoshi

    Hi Satoshi,

    Can you please let me know what CT capacitor, output capacitor, and load current the customer is using?  Also, could you specify what you mean by "concrete spec"?

    Thanks,

    Thank you for reply.

    Load current is 0.1A.
    CT capacitor and output capacitor is pending.
    ⇒Customer thinking that capacitor will examine our recommend capacitor value.

    "concrete spec" is t_on and t_rise spec on Vbias:3.3V condition.
    On the datasheet spec, Vbias:2.5V is NG, Vbias:5V is maybe OK.
    But Vbias:3.3V can't judge.

    Best regards,

    Hi Satoshi-san,

    Thank you for the additional information.  Once the customer provides the output capacitance I can provide some data using multiple CT capacitors.

    Out of curiosity, why is the customer using the TPS22966 for such a light current load?  The TPS22968 or TPS22960 are both dual channel devices which have lower current ratings and would be suitable for the 0.1A load.

    Thanks,
